Question 269173
It's a good practice to go step by step
She wants to earn $65,000 and she makes
$18,000, so
{{{65000 - 18000 = 47000}}}
She must get $47,000 in commissions. She
makes 3% on each house she sells, so
let {{{x}}} = the number of houses she must sell.
This is a flat commission- if it depended on 
the cost of the house, the problem couldn't 
be solved.
I'm not sure, but I think the 3% is 3% of $18,000
{{{.03*18000 = 540}}}
So she gets $540 for each house sold.
{{{47000/540 = 87.037}}}
She must sell 87 houses.
I'm not sure at all, but that's my guess
